PU High Resilience Material For Automotive Seats
DHR-A/DHR-B
CHARACTERISTICS
Blend polyol DHR-A is made up of polymer polyol, grafted polyether polyol, ccross-linking agent,
blowing agent and composite catalyst.
Isocyanate DHR-B is made up of modified MDI.
This composite can be used at the place which TDI is not allowed and mold temperature can reach 40- 50℃. The resulting product is eco-friendly and has low smell, high resilience and high hardness.
APPLICATION
This kind of product is widely used for making car seats.
